XTOOL D9EV EV Diagnostic Tool

The XTOOL D9EV is a professional diagnostic platform designed for electric vehicles, new energy vehicles and conventional automotive systems. It combines full-system diagnostics with advanced EV battery analysis, ECU coding, topology mapping, bi-directional control and key programming capabilities.

Designed for professional workshops, automotive technicians and EV specialists, the D9EV provides access to available vehicle control modules and can read and clear diagnostic trouble codes, display live data, perform active tests and support a range of service and maintenance functions.

For compatible electric vehicles, the D9EV can provide detailed battery pack information including total voltage, maximum and minimum cell or module voltage, voltage differences and battery temperature data. Tesla and BYD are among the EV manufacturers listed in the supplied coverage information.

The system also supports modern vehicle communication protocols including CAN FD and DoIP, while wireless Bluetooth and Wi-Fi connectivity provides greater flexibility during diagnostic work.

Important: Diagnostic, coding, battery analysis and special-function availability varies by vehicle make, model and year. Always confirm compatibility using the vehicle VIN before purchase.

EV Battery Diagnostics

The D9EV is designed to provide deeper diagnostic information for compatible electric vehicle battery systems than conventional OBD scanners.

Depending on vehicle support, battery diagnostics can display:

• Total battery pack voltage
• Maximum battery voltage and module location
• Minimum battery voltage and module location
• Voltage difference between battery modules or cells
• Battery temperature information
• Battery system and component information
• Battery module locations
• System block diagrams
• Component and connection information

The supplied package also includes dedicated Tesla battery pack adapters and universal jumper cables for supported diagnostic applications.

Battery diagnostic availability is vehicle-specific and does not mean the D9EV can diagnose every EV battery system.
